Deleting price blocks by/from a workflow

[Kouw, FA - SPLTX]

Hi,
 
I have the following problem:
 
When processing blocked invoices (blocked for price reasons) an invoice
(actually the work item) can be forwarded to all SAP users. The user to
whom the invoice is forwarded can choose from the following options:
 
   * Change PO
   * Delete price blocks
   * Cannot be clarified
 
When deleting price blocks the price blocks are actually deleted in a
background step (WF-BATCH). This way all SAP users that receive the
invoice (work item) are able to delete price blocks, what is what we
don't want.
 
I could turn the background step into a synchroneous step without dialog
under control of the previous user. In that case I would have to assign
the correct authorizations to that user for deleting the price blocks.
But we don't want users to have those authorizations, because this
enables them to use this function from the SAP report MRBR, which the
business doesn't want.
 
Does anyone have a suggestion how to solve this?
 
Regards,
 
Fred Kouw
